Hi,
Went to this dishwasher this morning, client says it was temperamental draining about 4 times.
During the tests, nothing obvious and it drains 6 times without issue. So I supplied the degreaser and left it to flush it out to see if this improves. Everything else works just fine.
My thoughts were that the machine is 12 years old, I doubt the pump is the real issue as it works every time as my experiences that when the drain pump goes it really do stop dead or make a right racket but never temperamental. Would I be thinking communication issues due to age? No reports of error codes.
